Do you have CWM actually installed?If not flash it via ADB below;
http://forum.xda-developers.com/showthread.php?t=2191285
Are you pressing the buttons to boot the device or after you have already booted the device?
-- Remove battery of your phone and reinsert.
-- Press Power and Volume Up key together to boot into recovery mode.
-- You should see CWM now, otherwise try flashing again

You are the guy who developed the custom ROM for A27 Bolt, right? How did you take the nandroid backup before flashing the new ROM? I have been meaning to ask you this.
If you have taken the backup using CWM recovery, then which process did you follow for flashing the recovery? Is it the one mentioned in this forum for A27 Ninja?

That defeats the purpose of the CWM recovery, as we need to be able to get into recovery when the phone is BRICKED, so I looked around for this kind of problems. I was using the ROM Toolbox Lite for rebooting into recovery. I am currently using the the following through ADB to boot into recovery when the phone is turned off, so it will also work on brick:
Code:
adb reboot recovery
As far as I understand, if I can extract init.rc ouf of boot.img, (init.rc opens with notepad) find “service flash_recovery /system/etc/install-recovery.sh” and comment it (put # before the line and the next lines in this paragraph or the next command), and then save init.rc and rebuild the boot image then flash the boot.img back, then we will be able to get CWM by pressing the power + volume up button.
The problem I am facing with this are 2:
There is a separate init.rc in my "System" directory, and it contains the line. Should I change this one or extract the init.rc out of the boot.img?
How to extract init.rc out of boot.img and after editing rebuild the boot.img?

If Micromax Bolt versions have same h/w configuration, switch off the phone, then press and hold VOLUME DOWN(-) button, and while press-holding it, press POWER button, keep holding both buttons. An 'exclamatory sign inside a triangle with a phone icon' should appear on the screen after 10-20 seconds. This is the recovery mode. Tested in Micromax Bolt A26. Connect the phone via USB cable to PC. Open ADB tool on command prompt, and type 'adb devices', it should list your phone with an ID and as 'Recovery' mode. This is the only way I found to interact with the Micromax Bolt phone, since I couldn't find any hard reset key combinations to show up the ClockWorkMod Recovery options on screen. Remember, incase if your phone is soft-bricked/bootloop stuck, and it is non-rooted and USB-Debugging disabled, chances to recover the phone OS and it's data is less, expect to FLASH it with a new compatible stock/custom ROM using Spreadtrum Tool and necessary PAC file using an Auto-Ignition Cable (This can be done without need for Flashing Box). If the phone is rooted/USB-Debugging enabled when it was bricked, then it can fixed just by using ADB tool to wipe cache/user data or any other ops, without necessity for flashing ROM.
